How can I convert an mp3 file to wav without losing metadata in ffmpeg?

This happens whether I convert from mp3 or if I'm re-encoding a wav file, it doesn't make a difference.

I tried adding -map_metadata 0 -id3v2_version 3 to my command but to no avail. Please help.

(using ffmpeg-4.1-win64-static)

    FFmpeg does not, at present, support writing id3 tags in WAVs.

    WAV doesn't support ID3 tags at all - only RIFF tags are allowed, embedding ID3 tags inside them is not portable.

  • @Eugen Rieck it worked in Foobar though, will it cause mp3-players with old firmware to crash due to a header discrepancy? (Not that I know what that is though (just heard that somewhere))

  • BWAV or RF64 might be able to do something close to what you need [I'm no codec expert so this is a bit of a guess, based on my DAW's export info abilities.]

  • @Emdosis Outdated MP3 Players will most likely either not play WAV at all or ignore RIFF tags.

As others mentioned, it's currently not possible with FFmpeg, as there is no standard method for saving ID3(v2) metadata in WAV files. There are indeed some non-standard ways to save ID3 tags in RIFF chunks. You can find a bit more info here.

There is an open ticket for FFmpeg that I created for another user who had a similar problem.
